New York filmmaker Andrew Filippone Jr. has chosen a righteous topic for a documentary: the Buick Grand National, the factory hot-rod that kept hope alive of a real renaissance within General Motors — rather incorrectly, in hindsight.

So far, the promo has a few grandees and graybeards of Detroit talking over the arrival of the GNX into the moribund world of mid-80s Buick dealerships. This makes us want to see video of GM's great turbocharged hope that much more.
